Hydronic High Performance Heaters

Hazloc HHP2 hydronic high performance heater is an industrial heater specifically designed to meet the harsh requirements of heavy industry.

The rugged design of the Hazloc HHP2 series makes it ideal for use in heavy-duty industries that include oil & gas, pulp & paper, power generation, mining, steel mills, foundries, water and wastewater treatment plants, chemical plants and hazardous material storage facilities.

The harsh conditions within these industries require equipment to be safe, reliable, dependable and able to be operated in industrial areas.

HHP2 heaters are suitable for a wide variety of heating fluids and are perfect for steam, hot water, or glycol applications.

They are also used with other non-lethal or non-poisonous fluids, as defined by ASME, for both space heating and liquid cooling applications that include but are not limited to hot-oil heaters, lube-oil coolers, product process coolers, pump-seal coolers, etc.

HHP2 heaters are available in either vertical or horizontal projection models.
